Description
Technical field
The utility model relates to a kind of vacuumizing device that is used for, a kind of specifically jet vacuum pump that is used to dewater, filter and absorb toxic and harmful.
Background technique
Jet vacuum pump is to be working medium with water, uses centrifugal water pump to be power, the water high velocity jet is obtained a kind of energy-efficient equipment of vacuum.But; Jet vacuum pump is widely used in industries such as light industry, chemical industry, pharmacy, chemical fibre, papermaking, food, oil, environmental protection, vacuum brickmaking at present; Often aspirate corrosive gass such as a large amount of strong acid and strong bases, these gases mix with circulating liquid, make circulating liquid also produce corrosivity; Heavy corrosion parts such as vacuum pump, orifice plate and water tank, greatly reduce working life of jet vacuum pump; Corroded the hole on the orifice plate in the sparger especially, can make the aperture become big, flow increases, and has a strong impact on the stability of vacuum pump operation.In addition, hole purpose quantity is unreasonable on the orifice plate of vacuum pump, also can cause horizontal intersection point malleable, and often backwater causes ultimate vacuum to descend easily, causes working efficiency low.
The model utility content
The purpose of the utility model just provides a kind of jet vacuum pump, existing jet vacuum pump is perishable to solve, working life weak point, fluctuation of service, ineffective problem.
The purpose of the utility model is achieved in that a kind of jet vacuum pump; Comprise water tank, motor, water pump, sparger, vacuum tank and base, said motor, water pump and water tank all are fixed on the said base, and said sparger is connected with water tank through Venturi tube; Be connected by first connecting tube between said water pump and the sparger; Said vacuum tank be connected by second connecting tube between sparger is suitable for reading, said water tank top is provided with the emptying flange, side wall upper part is provided with spill pipe; Lower sidewall is provided with blowdown valve; Water tank, sparger, water pump, first and second connecting tubes, sparger, orifice plate and Venturi tube are processed with anti-corrosion material, are provided with orifice plate in the said sparger, and said orifice plate is provided with 7～18 holes.
Said water tank, sparger, water pump, connecting tube, sparger, orifice plate and Venturi tube adopt glass fibre reinforced plastic material to process; It has cheap; Acid, alkali, salt and multiple oils and solvent to atmosphere, water and high concentration all have resistivity preferably, can significantly improve the operation stability and the working life of jet vacuum pump.
Said orifice plate is provided with 7～13 holes, and the circulating water flow velocity is concentrated, and intersection point is malleable not, and no recirculation water is increased work efficiency.
The utility model moulding advantages of simple, low cost of manufacture, and gas-liquid separation effect is good; Have spill pipe on the water tank; Keep jar interior water level constant, satisfied the operating conditions of water pump, and constantly added the continuous overflow of water; The working medium temperature can not raise, kept stable degree of vacuum and rate of air sucked in required.The use of reinforced plastics makes vacuum pump can satisfy technological requirement medical, chemical industry, has enlarged the application and the working life of vacuum pump, has reduced cost of production.The design of hole count can significantly improve the working efficiency of sparger on the orifice plate in addition, makes jet vacuum pump have stable degree of vacuum.
The utlity model has characteristics such as rational in infrastructure, corrosion-resistant, long service life, simple to operate, stable, working efficiency height, can be widely used in industries such as light industry, chemical industry, pharmacy, chemical fibre, papermaking, food, oil, environmental protection, vacuum brickmaking.
